Android Toolbar - How to implement Spinner for navigation mode?

Question

What is currently the correct way to implement the View Control (No. 2 from the below screenshot taken from Android's design guide):

I found this example but when I tried to replicate it, I noticed that methods like: actionBar.setNavigationMode() are already deprecated.

So how should I implement it? I thought at first that it's a Spinner but I see apparently that it's not exactly the same
and can I still use ActionBar or should I better move to use Toolbar (yes, I am confused...)

As you rightly said, the setNavigationMode() method is now considered passé. To get the spinner in API 21, you need to use the Toolbar in this way:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_actionbar"
    android:layout_height="?attr/actionBarSize"
    android:layout_width="match_parent"
    android:background="?attr/colorPrimary">

<Spinner
        android:id="@+id/spinner_toolbar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</android.support.v7.widget.Toolbar

Add the above code to your Activity's layout. To set up the Toolbar in this Activity, you need to do this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_layout);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
    setSupportActionBar(toolbar);
}

Try this. This will work.
